             Recommendations for DNSSEC Resolvers Operators
           draft-ietf-dnsop-dnssec-validator-requirements-00

Abstract

   The DNS Security Extensions define a process for validating received
   data and assert them authentic and complete as opposed to forged.

   This document is focused clarifying the scope and responsibilities of
   DNSSEC Resolver Operators (DRO) as well as operational
   recommendations that DNSSEC validators operators SHOULD put in place
   in order to implement sufficient Trust that makes DNSSEC validation
   output accurate.  The recommendations described in this document
   include, provisioning mechanisms as well as monitoring and management
   mechanisms.
